PROPELLER SHAFT AND UNIVERSAL JOINT
(2)
Remove the four bushing retainers from the
yoke (Figs.
2
and 3). Press one roller and bushing
out of the yoke by pressing on the opposite bushing.
(3) Press out the remaining roller and bushing as-
sembly by pressing on the end of the cross.
(4)
Remove the cross assembly from the yoke. Do
not remove the seal retainers from the cross. The cross
and retainers are serviced as an assembly.
Cleaning and Inspection
(1) Clean all the parts in a suitable solvent and dry
with compressed air. Examine the bearing surfaces of
the cross. They should be smooth and free from rip-
ples and pits. If the bearing surfaces or seal retain-
ers are damaged, replace the cross assembly.
(2)
Examine the rollers in the bushings. Rollers
that have operated on a worn cross should be re-
placed. Rollers should have a uniformly good appear-
ance and roll freely inside the bushings.
Assembly
(1) Lubricate the roller and bushing assemblies
with Universal Joint Grease, NLGI Grade 0. Also, fill
the reservoirs in the ends of the cross.
(2) Place the cross in the propeller shaft yoke, ob-
serving the identification marks made at disassembly.
Install the roller and bushing assemblies in the yoke,
matching the identifying marks (Figs.
2
and 3).
(3) Press both bushing assemblies into the yoke
while guiding the cross into the bushings. Press un-
til the bushing retainers can be installed in the
grooves in the bushings.
(4)
Position the remaining two bushing assemblies
on the cross. Install the retainer strap to hold the
bushings on the cross during installation of the shaft
on the pinion flange. Lightly tap the outer ends of the
bushings while rotating the cross to be sure the cross
and bushings operate freely.
